SEMI-SOLID METALLIC ADDITIVE FABRICATION WITH TEMPERATURE CONTROL USING FORCE FEEDBACK. September 7, 2017: US20170252820-A1

A control loop for extrusion of a metallic build material such as bulk metallic glass measures a force required to extrude the build material, and uses this sensed parameter to estimate a temperature of the build material. The temperature, or a difference between the estimated temperature and a targ ...

ENERGY DIRECTORS FOR ADDITIVE FABRICATION USING SEMI-SOLID METALLIC EXTRUSION. September 7, 2017: US20170252813-A1

A printer fabricates an object from a computerized model using a fused filament fabrication process and a build material. One or more energy directors such as ridges are formed in an exposed surface of the deposited build material to provide regions of high, localized contact force that can improve ...
